The team made it official on Monday, placing Bowman on the physically unable to perform list. The Niners also placed running back Marcus Lattimore (knee) on the non-football injury list.

The earliest the two can return is Week 7 in a Sunday Night Football matchup at Denver. The 49ers have a bye the following week, in case they have any reservations about Bowman's game condition.

Prior to the injury, Bowman was Around The NFL's choice for NFL Defensive Player of the Year. One of the league's surest tacklers and fastest linebackers, Bowman produced dominant performances when fellow All-Pros Patrick Willis and Aldon Smith missed time early in the season.
